MORRIS J. GARDNER, OF YORK, PENNSYLVANIA.

OSCILLATING STEAM-ENGINE.

Speccation of Letters Patent No. 9,954, dated August 23, 1853.

To all whom t may concern:

Be it known that I, MORRIS J. GARDNER, ot York, in the county ot' Yorkand State ot Pennsylvania, have invented a-new and useful Improvement onOscillating Steam- Engines; and I hereby declare that the tollowing is afull and exact description thereof, reference being had to theaccompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in the manner of introducing thesteam through circular tubes into the steam chest, and at the same timeconstituting these tubes the circle around which the cylinderoscillates, in the manner substantially set forth, and I do herebydeclare that the tollowing is a full and exact description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon. y

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

Upon the steam cylinder, made in the ordinary way, I construct and tixpermanently, a circular steam chest and packing boxes, making thejournal the center ot the segment of the circle which the tubesdescribe, and which the cylinder necessarily makes, as it oscillatesover these tubes.

On Plate No. l Figure l sets forth a front external view ot myimprovement. a, a, are the circular tubes through which the steam passesinto the steam chest and cylinder, being made stationary on t-he frame.ot the engine. o Z) are larger circular tubes attached to the steamchest, inclosing 'the circular steam tubes. These larger tubes, are otsufficient size to admit of the necessary packing, and also to glideover and around the circular steam tubes. c, 0, is the external platecovering the steam chest, and firmly secured by screws or bolts, passingthrough the steam chest into the body ot' the cylinder. In the middle ofthis external plate are two set screws (Z, d, tor the purpose ofadjusting a steel plate, back of the valve in the steam chest, to keepthe valve tight on the steam ports when the motion is reversed.

Fig. 2, on Plate No. l, represents the steam cylinder, with a side viewot the steam tubes-larger circular tubes and packing boxes.

Plate No. 2, Fig. l, gives an internal View of the whole improvement,showing the manner in which by means ot the circular steam tubes, thesteam is introduced into the steam chest and from thence into thecylinder. Also a view of the dissected halt of the larger tubes(constituting at the same time the packing boxes) which pass over thesteam tubes as the cylinder oscillates, and also a view of the packingby which it is secured from leakage. a, a, are the steam tubes, that onthe right hand the induction and that on the lett the eduction tube. C,is one of the steam ports for the admission of steam into thecylinder-the other corresponding steam port being hid from view by theValve connected with the eduction tube, as seen at c marked with dottedlines. C, also represents the valve connected with the eduction tube,which as the cylinder oscillates, alternately opens and closes the steamports, for the admission of steam into the cylinder and at the sametime, for the escape of the exhaust steam through the eduction tube.

Fig. 2 is a hollow tubular screw, through which the steam tubes pass, asthe cylinder oscillates. This screw is made to screw into the packingboxes attached to the steam chest, at the inner end of the screw, is aprojection which is hollow as seen at d.

Fig. 3 gives a side view ot the screw.

Fig. 4 gives a View ot the knob or top ot thejscrew. Into the hollowprojection of this screw, is inserted a self-adjusting ring, a littlesmaller than the hollow projection in the screw, so that it may readilyadjust itself, both to the packing and the steam tubes. This ring isbeveled on the inside so as to render more compact the packing, andpress it against the tubes.

Fig. 5 gives an end view of the screw with the ring in it.

Fig. 6 gives a side view of the ring, the dotted lines represent thebevel of the ring.

The manner in which these screws are inserted into the packing boxes isseen at e, c, and the manner in which the adjusting ring compresses thepacking, and presses it against the tubes, is seen at f, f. One of thesescrews is inserted at each end ot the circular steam chest and packingboxes.

To reverse the motion, all that is necessary will be to have an ordinarysteam chest communicating with the circular steam tubes and with a slidevalve, to make the educting the inducting, and the inducting provementmay also be successfully employed as a Water pump and a blower forfurnaces.

That I claim as my improvement is- The mode of introducing the steam-the:circular steam tubes, the circular steam chest and packing boxesoperating in the manner herein described. I do not however confine myclaim to the precise position or dimensions, of the various partsdescribed in the foregoingspecifications, but to use such positions anddimensions substantially the same, as may be best adapted to produce the20 desired effect.
